On all VW Group cars, the first brake fluid change is required at 3 years, then every 2 years after that, regardless of mileage run.
Edit:- also plan to use VW Group branded brake fluid or the equivalent from other suppliers of brake fluid, like TRW DOT 4 ESP etc and not just bog standard DOT4 which is normally a bit cheaper, eventually bog standard DOT4 will vanish as cars without ABS vanish.
